To all whom it may concern.

Be it known that I, GEORGE CoLmNsoN, a subject of the Kin of Great Britain and Ireland, residing at I3ristol, in the county of Gloucester, England, have invented certain new and useful Improvements in Domestic Washing Machines, of which the following is a specification. This invention relates to machines for washing clothes; and it consistsin the novel construction and combination of the parts hereinafter fully described and claimed, whereby the clothes are subjected to the action of hot water which is caused to circulate through the clothes in a suitable closed vessel.

In the drawings, Figure 1 is a perspective constructed according to this invention, with one side of the vessel broken away to show the devices insideit. -Fig. 2 is a perspective view of the cover of the 'vessel,'from below. Fig. 3 is a similar view of the cover, from above. 'Fig. 4 plan view of the removable perforated plate. Fig. 5 is a perspective view of the stationaiy perforated plate and circulating *ig. 6 is a detall perspective view of the vessel.

A main vessel 1 is provided, and is preferably a cylindrical can open at the top. The top of this vessel is closed by a cover 14 which an upper chamber for steam and water. A stationary perforated plate 2 is supported in the lower part of the vessel 1, and has a central upwardly projecting pipe 3 secured to it, and provided with branch pipes or outlets for water 9 which project laterally from the pipe 3 at different angles and elevations. This stationary plate 2 is supported in the means.

A movable perforated and it has a central hole over the upper part of the central pipe 3 above the branch pipes 9. The clothes to be washed are placed in the space between the plates2 and 4, and are covered with water.

An annular plate 13 is provided and secured in the cover 14, and forms the base of the upper chamber. The pipe 3 projects through the large central opening 15 in the plate 13. A guide pin 16 projects centrally from the top of thecover 14, and 17 is a crosshead which is slidable on the pin 16 outside the cover. Two parallel rods 7 are secured to the crosshead, and are slidable in holes in the top of plate 4 is provided,

the cover, and have an annular regulating Serial No. 453,775. a

disk secured to their lower ends above the plate 13. The hole 18 in the disk 12 is slidable over the upper end portion of the central pipe 3, and when the regulating plate is pushed down it closes the opening 15'of the plate 13. An outlet opening 8 for steam is.

providedinthe upper part of the cover 14.

' A curved'outlet pipe 11 for water is pivoted at one side of the cover close above the annular plate 13. When the curved pipe 11 is turned downwardly, as shown in full lines any water above the plate When the curved pipe is as shown by dotted lines 13 is drained ofi'. turned upwardly,

10 in Fig. 1, the water is retained above the plate 13. The pipe 11 will retain water in the vessel at a predetermined level above the plate 13. When the plate is pushed down to close the opening 15, the water that boils over the top of the space above the plate 13, and can be let out by turning the pipe 11 downwardly. The plate 12 and pipe 11 afford a means for maintaining a predetermined high water vessel, and for preventing the return of water from the top of pipe 3 without affecting pipes 9. The vessel is placed over a'suitable source of heat, such as a fire, and the water pipe 3 is trapped in the the action of the lateral branch below the stationary perforated plate is heated and caused to rise through the central pipe, and is circulated through the clothes by means of the'branch pipes and the perforations of the stationary perforated plate. Some water and steam pass out at the top of the central pipe, and this water is discharged onto the clothes when the plate 12 is raised. When there is too niuch water in the vessel the surplus water is let out by the pipe 11. The late 4 'has notches or slots around its centra hole, so that it may slide over the ranch pipes 9, and when turned around a little it will be locked from rising by the pipes 9, and can be used under pressure.

What I claim is:

1. In a washing machine, a vessel for holding clothes and water, a perforated plate in the lower part of the vessel, a pipe which projects upwardly from the said plate and which has a series of water delivery pipes which project laterally from it and distrib ute hot water between slidable on the said to confine the clothes which has a series of w'ater delivery pipes which project laterally from it at different levels and which distribute hot water between the clothes, and an upper perforated plate slidable and revoluble on the said pipe and provided with notches which slide over the said lateral pipes and enable the upper plate to be retained by them at various levels above the lower plate. I

3. In a washing machine, a vessel for holding clothes and water, a stationary plate arranged, in the lower part of the vesseland provided with an upwardly rojecting pipe, a perforated plate slidable on the said pipe above the clothes, a plate supported in the upper part of the vessel below the top of the said pipe and forming with it anannular opening, a plate slidable over the upper end portion ofthe said pipe and adapted to close the said annular opening, and means for drawing 0E surplus water from the upper part of the said vessel.

4. In a washing machine, a vessel for holding clothes and water, a stationary perforated plate arranged in the lower part of the vessel and provided with a central pipe for hot water having lateral outlets, a movable perforated plate slidable over the said pipe, a hollow cover which closes the top of the said vessel and which has an annular base plate through which the central pipe projects, means for closing the opening in the said base plate at will, and means for draining oil the water from the hollow cover.

5. In a washing machine, avessel for holding clothes and water, a stationary perforated plate arranged in the lower part of the vessel and provided with a central pipe for hot water having lateral outlets, a movable perforated plate a hollow cover which-closes the'top of the said vessel and which has an annular base plate through which the central pipe projects, an ,annular regulating disk slid-able over the upper end port-ion of the said central pipe and adapted to close the opening in the said base plate, means for raising and lowering the said disk, and means for draining off the surplus water from the hollow cover.

In testimony whereof I have affixed my signature.
